Abstract Statistical mechanics of massless thin rings carrying electric charge is formulated. The rings are circular, concentric around a common axis, and can undergo axisymmetric deformations. The model is applied to guiding center plasmas confined in a toroidal magnetic field, where charged rings are identified with flux tubes. It is argued that the steady state of such systems can be viewed in terms of the dynamics of these rings that slide on equipotentials and go through each other. A partial differential equation describing the most probable distribution of charges on the rings is obtained and solved numerically. Solutions corresponding to an ensemble with charges of single species and two species are obtained. The results show that the statistical mechanics of these rings differ in interesting ways from that of line charges. {copyright} {ital 1996 American Institute of Physics.}
